How to Restore the Original Desktop Background in Windows XPby Daniel Hatter
Windows XP comes with a number of pre-installed wallpapers for use as desktop backgrounds. They are located in the "Display settings" utility. Users may select any of these default pictures as a background, but may also use custom pictures, such as family photos, adding a level of customization to the Windows XP experience. A user who has changed the original desktop may restore it to its original background.
Open the Microsoft Display utility. Click "Start," then "Control Panel," then "Display." Open the "Desktop" tab once inside, if necessary.
Scroll through the list of pre-installed desktop backgrounds until you find the original background you seek. Click on it to select it, then select the position for the image. Your options will be "Center" (centers the image on your desktop), "Tile" (positions the image at the top left corner and repeats it as necessary to fill the screen) and "Stretch" (stretches the image to fill the screen).
Click "Apply," then "OK" to save your changes and exit the Display utility. Your original desktop background is now restored.
